IMPROVEMENT IN SWAGES FOR ZINC WASH-BOARDS.

Specification forming part of Letters Patent No. 38,4 l0, dated May 5,1863.

To all whom t may concern.-

Be it known that we, JOHN POOLE and THoMAs J. PnTTIN, of the town ofHarmar, in the county of Washington and State of Ohio, have invented anew and Improved Swage for the lI/Ianufacturing of Zinc Vaslr Boards;and we do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

Figure 1 is a perspective view of the machine complete, with the dropraised. Fig. 2 is a vertical section through the center of the machine,showing sides of the frame, and the die-swages, bed-plate, snail-wheelor cam,and the position of the legs. Fig. 8 is a side of the die-swage.Fig. 4 is a top view of the bedplate. Fig. 5 is a side view ofthesnail-wheel. Fig. 6 is an end View of the die-swage.

Our swaging-machine consists'of a strong metal frame, A, Fig. 1, fourfeet six inches in length and fourteen inches in width. The widths ofthe sides and back end are equal, (seven inches in width.) About seveninches from the front end is a cross-tie, (not seen in drawings) overwhich, from the front end fourteen inches back and even with the uppersurface, is a solid plate, B, Fig. 1, forniing a part of the frame. Tothis plate is fastened by screw-bolts from the under side of acorrugated bed-plate, C, Figs. 1, 2, and 8, of the size and shape of ourwash-board plates. To the main body of this frame are four legs, D D D,Figs. 1 and 2, firmly fastened.` At or near the lengthwise center of themain frame are propel1 boxes or bearings E, Fig. 21 upon which arevolving shaft, F, Fig. 1, is placed. Upon this shaft is a snail-wheelor cam, G, Figs. 1, 2, and 5, firmly fastened. On the outer end ofsaidshaft a cog-wheel, H, about thirty inches in diameter, is fastened, intowhich gears a pinion (not shown) five or six inches in diameter,fastened to a shaft, (not shown,) which also rests upon bearings on theside of the main frame, in like manner and parallel with thefirst-mentioned shaft. On the'extreme outer end of this last-mentionedshaft, and against the pinion, is a pulley, I, Fig. 1, of any desiredsize. At the back end ofthe said main frame are boxes or bearings K,Figs. 1 and 2, on which rests and moves the end of a weighted lever ordrop, L, Figs.

1 and 2, which is also'of width, length, and shape to correspond withthe said main frame, except the front end. Across this drop-frame, rightover and parallel with the first-mentioned shaft, is a strong bar, M,Figs. 1 and 2,-against which the snail-wheel Gworks. The forward end ofthis lever or drop Lis of an arched form-that is, it is made open in thefront, so that the operator can put in his hand to adjust the zinc plateupon the bed-plate O, and hold it while the drop falls. In each side ofthe said opening or arch of the drop are dies N, Figs. 1 and 2, fastenedin grooves by teniper-screws. These dies are of the same length of thecorrugated bed-plate C, having `corresponding corrugations half acrossthe width of face, the balance beinglevel or smooth on a line with theextreme edge ofthe corrugations,so as to exactly correspond with theshape of the bed-plate C, that when the weighted lever or drop falls onthe already corrugated zinc plate lying on the bed-plate C the ends ofthe corrugations of zinc are all swaged to a straight line with theextreme line of corrugations, each end at the same time. rThis being theimportant feature of our machine, We will further explain the mode ofoperating the same. The operator takes the corrugated plates of zinc,places one at a time upony the corrugated bed-plate C, and properlyadjusts it by his hand upon the top of it, the plates being heldsidewise by proper guides. rlheweighted lever or drop L is then let fallwith its whole weight upon the aforesaid zinc plate, instantlytransforming the ends from a corrugated to a straight edge in line withone extreme side of the plate, thus fitting it to enter a groove cut inthe sides of the wash-board frame, and being formed into such a shapethat water will not enter freely said grooves, nor will it remain thereshould it enter.

Inthe upper part of the before-mentioned drop Lis an opening or cell, O,Fig. 1, to admit of the placing in of any additional weight that may berequired. At the extreme forward end of the drop L are little lugs orcatchesl? l?, Figs. 1 and 2. Corresponding lugs, R R, Figs. 1 and 2, areon the under or main frame, to which are attached arms or standards W W,Fig. 1, by screw-bolts, so as to play freely to and from the saiduppercatches. These arms extend above the extreme elevation of said dropL, and are connected at the top by a rod, S, Fig. 1, reaching acrossfrom one to the other, and firmly fastened by secrewnuts at each end.These arms are held up against the catches by a strong spiral spring, U,Fig. 1, fastened to said rod S, and extending back over the drop to asimilar rod, T, fastened to two stationary arms or standards, V V, Fig.

l, in like manner to the first mentioned.

The operation of our swaging-machine is as follows: A belt being putupon pulley I, motion is given to the main shaft F. The snailwheel G isbrought in contact with the bar M of the drop L, and as the'snail-wheelis moved around the drop is raised to its extreme height, when thecatches l? on the drop L are caught by the arms XV, having catches orshoulders for that purpose. The Zincplateis then placed to its properposition. The snail-wheel moving slowly gives time for the operator toadjust `the zinc. The arms W W may be held back, continuing theoperation regularly, but

should the operator desire to stop the working of the drop L he only hasto release his hold onthe arms WIW, and they will hold the drop fromfalling, thus stopping the machine. The snail is made to move as fast asthe operator can conveniently adjust the zinc, thus giving great speedto the operation.

After having thus fully described our invention, what we claim as new,and desire to secure by Letters Patent, is-

The bed-plate C, the weighted lever-drop L, in combination with the camor snail-wheel G and spring-catches W W, in the manner and for thepurpose set forth.
